where do they come from

[orin]

Maybe this is a stupid question but right around sunset my graph will load up with fish which seems odd after marking very very few fish all day long, where do they come from? Are they laying on the bottom? Do they come in from way out, if so you would think you would mark some as they are coming in? Are they staying away from the boat signature till low light? Most of the time I might as well pull lines at that point because I can't get em to bite. What are they?

I've read that small shrimp like creatures come up to feed which draws bait which draws fish.

A lot of those fish are White Fish. They lay on the bottom all day, and rise at dark to feed.
